Regioselective anti-carbometalation of alkynyl sulfides via the use of InBr3 and organosilicon nucleophiles to give β-mercaptoalkenylindium compounds was developed. The structure of β-mercaptoalkenylindium was characterized by X-ray crystallog. anal. A variety of disubstituted alkenyl sulfides were regio- and stereoselectively obtained by either halogenation or Pd-catalyzed cross-coupling with aryl halides using the mercaptoalkenylindiums. In the experimental materials used by the author, we found Indium(III) bromide(cas: 13465-09-3Category: bromides-buliding-blocks)
Indium(III) bromide(cas: 13465-09-3) is used in organic synthesis as a water tolerant Lewis acid. It efficiently catalyzes the three-component coupling of β-keto esters, aldehydes and urea (or thiourea) to afford the corresponding dihydropyrimidinones.Category: bromides-buliding-blocks
